Mi Digital High Torque Metal Gear Servo JR/Hitec 11.8kg / 0.07 / 61g
The HK Mi Series servos represent the next break through in high precision servo technology. Using Magnetic Induction, rather than a potentiometer, for an unsurpassed level of accuracy and performance.
I use two of these servos with mag encoder. Once they are seperated from each other, they work fine. But installed in a small plane, where they have to be placed one by one very near, one servo is moving fast fore and back when the other one is steared by radio and vice versa. Is it possible, that there is a magnetic interference to the encoder may be produced by mag. field of motor from other servo?
Don't run these at over 280hz, the digital amplifier can handle the frequency (as per the specs on blue Arrow's website) but the servo's heat dissipation isn't enough to get rid of the excess heat and it will cook itself to death, especially if used on a gyro. Stay at 250hz and it's a good servo.
I have 3 of these on my heli swash plate. 1520pulse 333hz. They chatter a lot! And when I load 1 servo, they start chatting more and even all of them start to go back and forward quickly a few degrees, fighting to keep their position. These are BlueArrow servos, I'll check up the specs there also.
I hope another setting keeps them quiet and keep their position.
It may be a combination of the frequency and your gyro. I would try dropping down to 250hz and see if that fixes it. On cyclic servos the difference in performance between 250hz and 333hz is basically non existent.
Whats the dif. between this one and the red case one other than the hight? They have the same specs, so why would you want a taller servo that does the exact same thing? red one is model#HK47011DMG
Thanks you, whoever answers this.
According to the vendor, that should be great for steering on big planes and RC 1/8 class cars.
HK could you also please copy the application notes from the vendor? It would be easier than going there and looking up everything :)
1 thumbs up!
Short: I got this servo and am very happy with it.
Long: At first I ordered one for a short course truck dedicated to bashing. Been using it for 3 months now for steering, some replaced parts on the truck however no problems ever with the servo. This Mi servo is very strong and fast and so far has been totally reliable. About a month ago I ordered another one of these servo for a different SC truck used for racing. Have run the 2nd servo for a couple weeks now and it works great, no issues like the first one. Well since the first two were good I just ordered a 3rd Mi servo to upgrade the BMS-661DMG steering servo of my 1/10 drift car. The 661D is cheaper but this Mi servo is faster, smoother and higher torque headroom for my application. Me like it!

Tested this servo only once, it's working great, really fast...
It only needs to last for a good time to be an excellent servo.

Nach mehr als 100 (schonungslosen) FLUEGEN als TS-Servo am T-Rex600 FBL (Direktanlenkung) kaum Spiel und ohne jegliche

Ils paraissaient pourtant prometteurs...3 servos montés sur un T-Rex600, utilisé en 3D hard: 1 servo a bloqué d'un coup, après démontage, il y avait un axe en trop qui promenait dans les pinions, le deuxième a du couple dans un sens mais presque rien dans l'autre sens, et le troisième ne démarre qu'après avoir un peu tourné le palonnier! Voilà, l'hélico est encore entier mais c'est un miracle...
